This is a set of number talk dot-cards.
Dot-cards are a good introductory activity for introducing number talks to your students. Number talks are a great activity for students to do to help assist them with their number sense. The basic idea behind number talks is to have students discuss various ways to solve calculation problems. Dot cards help introduce that concept to students by allowing them to be able to visualize different ways to groups objects together.
To use them you simply show students a card with a collection of dots on them. Then have the students count how many dots are on the card, by any method they would like to except for counting by 1s. For example, if you showed them a card that has 8 dots on it, they could count it as 4+4 or 2+2+2+2 or 2+6, or any combination that adds together to get 8, just not doing 1+1+1…..
This set of activities is probably best done with lower elementary students, but I have also used these cards with my 7th and 8th grade students. They had not practiced number talks before and thus were a bit confused on the concept and this was a great introductory activity for them.
This packet contains one page of an explanation and 30 pages of dot cards to display for students.
